Usually, the technician, nurse, or doctor will have you sit down on a chair with your feet on the ground.

This might seem scary, but it's quite straightforward. Or, they can explain why you've been "feeling off" for the last few months.
Getting blood taken can be scary for those who've never done it, especially children. That's why doctors encourage their patients to get routine blood work done.
By analyzing the blood, scientists can detect illnesses before it's too late. Often you're done in less than five minutes.
What Can Blood Tests Detect? The reasons for getting your blood tested vary. Blood can tell you about your organ function, diet, metabolism, illnesses, and if you have certain diseases. You likely have lots of questions about the process and results.
A routine blood test consists of getting blood taken at your doctor's office or at a lab. It can tell you hundreds of things about your lifestyle and habits. In a routine blood test, it might just be to check that nothing has changed since your last healthy test result.

This type of inflammation is usually helpful. Chronic infections, certain autoimmune disorders, and other diseases can cause harmful chronic inflammation. High levels of CRP may mean you have a serious health condition that causes inflammation.
Inflammation is your body's way of protecting your tissues and helping them heal from an injury, infection, or other disease. Normally, you have low levels of c-reactive protein in your blood. Inflammation can also happen inside your body.
If inflammation lasts too long, it can damage healthy tissues. But the test can't show what's causing the inflammation or which part of your body is inflamed.A c-reactive protein test measures the level of c-reactive protein (CRP) in a sample of your blood. CRP is a protein that your liver makes. This is called chronic (long-term) inflammation. Your liver releases more CRP into your bloodstream if you have inflammation in your body. Those are signs of inflammation. Inflammation can be acute (sudden) and temporary. Chronic inflammation can also happen if your tissues are repeatedly injured or irritated, for example from smoking or chemicals in the environment.
A CRP test can show whether you have inflammation in your body and how much. For example, if you cut your skin, it may turn red, swell, and hurt for a few days.
